Waste Vegetable Oil Fuels Buehler's Latest Green Project

WOOSTER, OHIO — Jay Larkin, the corporate chef for Buehler Food Markets here, drives to the retailer's 13 stores to oversee its restaurant operations in a Volkswagen Jetta TDI. The Jetta normally runs on diesel fuel, but for the past six months it has been using a different kind of fuel — waste vegetable oil (WVO), taken from the stores' kitchens.
